原生地・分布（英語）:

説明（英語）: Genus of 10-15 species of monoecious, marginal aquatic herbaceous perennials from temperate and tropical regions worldwide. They form dense, robust stands of vegetation around lakes and large ponds. Thick rhizomes spread in shallow water, producing long, linear, mostly basal leaves and poker-like brown flower spikes, borne among the foliage but overtopped by the leaf tips. Clusters of male and female flowers are produced on the same spike. Bulrushes are usually only suitable for planting around a large wildlife pool, where deep water prevents their spread; T. minima is the only species suitable for a small pool or tub. The flower spikes are used in dried flower arrangements.
